How BA284 actually runs

Pro Flight Search has tracked every published board update for BA284 across the SFO and LHR boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 3 completed legs so far: left a little late (~8 min) but landed about 8 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how BA284 operates rather than what the timetable promises. Numbers refresh as new flights operate.
